My nephew and I enjoyed very much staying at Helene's; the flat was really a good choice: clean, quiet, comfortable, well equipped. The position, out of the busy centre, was for us good, instead of being a downside: we liked walking in the morning to the bus stop (12 min), to the ShowDC (15 min) or to the Pier (20 min); of course one could also take a motorbike taxi, but we were never in a hurry, so we didn't.
And Helene is really very kind: she was always ready to help us, in case, even if we had no problem at all during our stay.
I hope Helene's flat will be not occupied, if I'll happen to spend again some days in Bangkok.
